SPECIFICATION forming part of Letters Patent No. 491,482, dated February7, 1893.

Application filed June 20, 1892. Serial No. 437,263. (No model.)

To all whom it may concern.-

Be it known that I, CALEB E. HEALY, a citizen of the United States, anda resident of Detroit, county of Wayne, State of Michigan, have inventedcertain new and useful Improvements in a Combined SteanrMuifler andHeating Apparatus, of which I hereby declare the following to be a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in combined steam mufflers andheating apparatus for railway service, and is designed as an improvementupon the invention described in Letters Patent granted to me upon steammufflers, dated March 31, 1891, in which apparatus for absorbing exhauststeam, is shown in combination with a high pressure engine, and bearingthe number 449,120.

This invention relatesto further utilization of the exhaust to heatingtrail cars, and consists in the combination and arrangement of parts andconstruction of details as hereinafter described, shown in the drawingsand more specifically pointed out in the claims.

In the drawings Figure 1 is a sectional view of amotor and trail car,showing the arrangement of heating pipes and their connections withthe'steam drum. Fig. 2 is an enlarged View of connections, in verticalsection. Figs. 3 and 4 are details.

A in the drawings represents the engine. 13, the steam pipe; 0, thesteam condensing drum; D, the final drum for rarefied steam inclosed inthe jacket D; E, the exhaust pipe leading into the space above thesubmerged tubes; E, the coil perforated at c for distributing the steamover the flue openings.

F is the funnel shaped space for concentrating the vapors above thefines.

G is the high pressure boiler.

H, is the fines.

I is the fire box and .I is the ash-pit.

In small letters a is the steam chest of the engine.

I) is the extremity of the exhaust pipe elcvated above the bottom of thedrum C.

c is a tube connecting the two drums.

c is the drip tube discharging the condensed steam from the bottom ofthe drum 0 at G into the ash-pan J; d is a similar tube connecting thedrum D and ashpit J.

at is a stop valve in the tube 0 and 11 the valve in the tube d cl, d,are semi-partitions arranged at intervals in the tube D to complete thedischarge of the moisture from the steam and d are the perforationsthrough the said partitions arranged upon alternate sides of the tube Dto give a zig-zag course to the ascending steam and insure its impactagainst each successive partition.

K, is a tube leading from the drum 0 at a suitable height to receivepure dry steam. This tube is branched at 7; and each branch as L, M, isprovided with a outoit valve as K, K The Y thus formed is extended intwo branches to either end of the motor car, where the extremities areprovided with steam pipe couplings 0.

It will be seen in the figures that the motor is designed to run ineither direction and that a steam heating pipe R is laid in coils underthe seats of the trail cars, the extremities of the pipe in the carsbeing left open in the direction of the engine. One of these extremitieswill be seen to be coupled directly to the open end of the exhaust pipeon the adja cent end of the engine, the other extremity of the heatingpipe being coupled to the pipe P which is placed in the motor anddischarges into the ash-pit J, and provided with couplings 0'. It willtherefore be seen that a constant current of heated vapor will be forcedcontinually from the exhaust drum of the engine throughout the trail carand returned in a more or less condensed form into the ash pit, where itwill not create an offensive dripping as in the well known forms now inuse where the exhaust for heating purposes is delivered underneath thecar in which it is used and condenses in a constantly dropping stream ofwater, which for city or suburban lines would be unsightly in theextreme.

The style of motor shown being adapted to move in either direction it isessential that the couplings for the exhaust pipe should be duplicatedat either end and upon a change in the direction of travel the trail caror cars are attached at the other end of the motor and the other branchof the Y in the pipe is conpled to the heating pipe. A second section ofpipe P, connecting the outlet end of the heating pipe With the ash pitI. lVhen in use the valve in the open branch is closed the otherremaining open.

The advantages of the device appear in its neat-ness, simplicity andslight initial cost, as well as efficiency in use.

If desired for the use of several trail cars in succession, the pipescan be connected in each car with the next by means of pliablecouplings, the final outlet being in the ash-pit as before described.

I do not claim any special arrangement of the heating tubes in the caror form of couplings but That I claim as new and desire to secure byLetters Patent is:

1. In combination with the drum or drums of a steam muffling device,substantially as described, an exhaust pipe leading from one of thedrums and terminating in two branches provided with cut off valves,substantially as described.

2. In combination with a high pressure boiler, engine and steam mufl'lerfor exhaust, substantially as described, an exhaust pipe leading fromone of the muffler drums at a distance from the bottom, and terminatingin two branches provided with stop valves, and outlet sections of pipe,projecting within the boiler ash-pit, substantially as and for thepurpose set forth.

In combina ion with a boiler, engine and steam exhaust muffler, providedwith vertical condensing drums, substantially as described, an auxiliaryheating pipe leading from one of the drums at a distance from the bottomof the drums, branches leading from the pipe in inserted in the ash pitof the boiler, and outer ends provided with pipe couplings,substantially as described.

4. In combination with an engine, boiler, and exhaust steam mnfiierdrums, located upon a motor car, an auxiliary exhaust pipe leading fromone of thedrums at a point above the drip out-let, branches providedwith stop valves leading from said pipe to either end of the motor carand provided with couplings. Open sections of pipe leading from eitherend of the motor car to their terminals in the ash-pit under the boiler,and a system of steam heating pipes, adapted to connect one of saidbranches with one of said ter1ninal sections, the valve in the branchpipe completing a continuous heating device, being opened, and the valvein the open branch being closed, substantially as and for the purposeset forth.

5. In a steam car motor, a steam muiiier for the exhaust consisting invertical drums into which the exhaust steam is discharged from below insuccessive series, the last drum of the series being provided withpartial partitions, having alternating openings, drip pipes from thedrums having outlets "in the ashpit of the steam boiler, a final exhaustpipeleading from the last drum of the series and disposed in a coil overthe boiler tube openings, in combination with an auxiliary steam pipeleading from one of the drums and provided with one or more outlets, anda system of steam heating pipes, detachably secured to one outlet ofsaid auxiliary pipe and to an open section of pipe discharginginto theash pit of the boiler, all as and for the purpose set forth.
